Abstract

The present invention provides therapeutic methods for treatment of conditions including the neutralization of the anti-coagulant activity of heparin, inhibition of angiogenesis, tumor and endothelial cell proliferation, and treatment of chronic inflammatory diseases by administration of bactericidal/permeability-increasing (BPI) protein products.

Description

BACKGROUND OF THE INVENTION

The present invention relates to therapeutic uses of bactericidal/permeability increasing (BPI) protein products for the treatment of conditions not directly associated with gram negative bacterial infection including neutralization of the anti-coagulant properties of heparin, inhibition of angiogenesis, tumor and endothelial cell proliferation and treatment of chronic inflammatory disease states such as arthritis.

HEPARIN BINDING

Heparin is a heterogenous group of straight-chain anionic mucopolysaccharides, called glycosaminoglycans having anticoagulant properties. Although others may be present, the main sugars occurring in heparin are: (1) α-L-iduronic acid 2-sulfate, (2) 2-deoxy-2-sulfamino-α-D-glucose 6-sulfate, (3)β-D-glucoronic acid, (4) 2-acetamido-2-deoxy-α-D-glucose, and (5) α-L-iduronic acid. These sugars are present in decreasing amounts, usually in the order (2)>(1)>(4)>(3)>(5), and are joined by glycosidic linkages, forming polymers of varying sizes. Heparin is strongly acidic because of its content of covalently linked sulfate and carboxylic acid groups. Heparin is found within mast cell granules and is released upon degranulation. A cell associated form of heparin is termed heparan sulfate. Heparan sulfate is a broad term used to describe a variety of sulfated proteoglycans (HSPG's) found with a near-ubiquitous distribution on mammalian cell surface membranes and in the extracellular matrix. HSPG contains a variable percentage of pentameric heparin-like sequences that function in a similar fashion as soluble heparin. The HSPG's serve as a repository for antithrombin III (ATIII) and for heparin-binding growth factors such as fibroblast growth factors (FGF) 1-5, IL-8, GM-CSF and IL-3. Folkman et. al., Inflammation: Basic Principles and Clinical Correlates, 2d Ed. Chapter 40, pp 821--839 (1992). In fact, cells made genetically deficient in HSPG's require exogenous heparin for growth.

Heparin is commonly administered in doses of up to 400 U/kg during surgical procedures such as cardiopulmonary bypass, cardiac catherization and hemodialysis procedures in order to prevent blood coagulation during such procedures. The anticoagulant effect of heparin in blood is a result of the interaction of heparin with ATIII. The heparin/ATIII complex is a potent inhibitor of many of the clotting factors of the coagulation cascade. Specific inhibition has been demonstrated for activated Factors IXa, Xa, XIa, XIIa and thrombin. The heparin/ATIII complex has the highest affinity for Factor Xa and thrombin which are common to both the intrinsic and extrinsic clotting pathways involved as the last two steps of the clotting cascade that results in the conversion of fibrinogen to fibrin.

When heparin is administered for anticoagulant effects during surgery, it is an important aspect of post-surgical therapy that the effects of heparin are promptly neutralized so that normal coagulation function can be restored. Currently protamine is used to neutralize heparin. Protamines are simple proteins of low molecular weight which are commonly isolated from salmon sperm. They are rich in arginine amino acid residues and strongly basic. Administered alone, protamines (usually in the form of protamine sulfate) have anti-coagulant effects. When administered in the presence of heparin, a stable complex is formed and the anticoagulant activity of both drugs is lost. Significant hypotensive and anaphylactoid effects of protamine have limited its clinical utility.

Other reported compounds which have heparin binding activity include platelet factor 4 (PF4) and major basic protein, see U.S. Pat. No. 5,086,164. Major basic protein demonstrates heparin binding activity but is also highly toxic.

Angiogenesis

Angiogenesis is closely associated with endothelial cell proliferation and constitutes the development of new capillary blood vessels. As such, it is an important process in mammalian development and growth, and in menstruation processes. The release of angiogenic growth factors, such as fibroblast growth factors 1 -5, induces proliferation of endothelial cells via a heparin-dependent receptor binding mechanism. See Yayon et al., Cell, 64: 841-848 (1991). These heparin-binding growth factors can be released due to vascular trauma (wound healing), immune stimuli (autoimmune disease), inflammatory mediators (prostglandins) and from tumor cells.

Angiogenesis is also associated with a number of pathological conditions in which it would be desirable to inhibit such new blood vessel development. As one example, angiogenesis is critical to the growth, proliferation, and metastasis of various tumors. Other pathological conditions associated with angiogenesis include diabetic retinopathy, retrolental fibroplasia, neovascular glaucoma, psoriasis, angiofibromas, immune and non-immune inflammation including rheumnatoid arthritis capillary proliferation within atherosclerotic plaques, hemangiomas, endometriosis and Kaposi's Sarcoma.

Folkman et al., supra, discloses that psoriatic lesions in the skin are dominated by epithelial proliferation, neovascularization, and an infiltrate of inflammatory cells. It is unclear, however, whether angiogenesis is a step in the pathogenesis of psoriasis or a secondary phenomenon.

Several substances are known to function as angiogenesis inhibitors and have been reported to inhibit tumor angiogenesis, to prevent the onset of arthritis and to inhibit established arthritis in collagen-induced arthritis models, Peacock et al., J. Exp. Med., 175, 1135-1138 (1992). As one example, protamine is known to inhibit tumor angiogenesis and subsequent tumor growth. According to Taylor et al., Nature, 297: 307-312 (1982) protamine's anti-angiogenic activity is attributed to is ability to bind heparin. PF4 is also known to exhibit anti-angiogenic activity. Of interest to the present application is U.S. Pat. No. 5,112,946 which discloses modified PF4 and analogs thereof which have anti-angiogenic activity but lack the ability to bind heparin. PF4 has been shown to have at least two functional properties. Heparin binding has been studied most extensively, however, PF4 was originally described to have collagenase inhibitory properties. Collagenase inhibitors were the first inhibitors of angiogenesis to be discovered in 1973. See Folkman, supra. The mutations in the heparin binding region of PF4 were not examined for their effect on collagenase inhibitory activity. Interestingly, thrombospondin is also an inhibitor of angiogenesis and binds to heparin with a serine/tryptophan motif instead of a basic amino acid motif. Thus, there is no obvious prerequisite for heparin binding or for angiogenesis inhibition.

Published PCT patent application WO 92/01003 discloses the use of glycosaminoglycan (heparin) derivatives and their use as inhibitors of tumor invasiveness. Heparin derivatives are disclosed which are described as being substantially devoid of anticoagulation activity and which impede the formation of tumor metastases in a host.

Chronic Inflammation

Chronic inflammation is usually supported by angiogenesis. Arthritis is a chronic syndrome characterized by the inflammation of the peripheral joints accompanied by synovial thickening and the influx of immune factors and cells such as polymorphonuclear leukocytes (PMN). In rheumatoid arthritis, the inflammation is immune driven while in reactive arthritis, inflammation is associated with infection of the synovial tissue with pyogenic bacteria or other infectious agents. Folkman et al., supra, also note that many types of arthritis progress from a stage dominated by an inflammatory infiltrate in the joint to a later stage in which a neovascular pannus invades the joint and begins to destroy cartilage. While it is unclear whether angiogenesis in arthritis is a causative component of the disease, and not an epiphenomenon, there is evidence that angiogenesis is necessary for the maintenance of synovitis in rheumatoid arthritis. While nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids and other therapies have provided improvements in relief for treatment of arthritis, there remains a need in the art for more effective therapies for arthritis and other inflammatory diseases.

Inflammation and angiogenesis are now understood to be separable but not mutually exclusive processes. Specific angiogenic proteins have been discovered that stimulate angiogenesis without inflammation and angiostatic steroids can inhibit angiogenesis without decreasing acute inflammation. See Folkman, supra. Interestingly, endotoxin has been identified as the most potent exogenous stimulator of angiogenesis through its stimulation of macrophage cytokines and growth factors.

Bacteicidal/Permeability-Increasing Protein

Bactericidal/permeability-increasing protein (BPI) is a protein isolated from the granules of mammalian PMNs, which are blood cells essential in the defense against invading microorganisms. Human BPI protein that has been isolated from polymorphonuclear neutrophils by acid extraction combined with either ion exchange chromatography [Elsbach, J. Biol. Chem., 254: 11000 (1979)] or E. coli affinity chromatography [Weiss, et al., Blood, 69: 652 (1987)] is referred to herein as natural BPI and has potent bactericidal activity against a broad spectrum of gram-negative bacteria. The molecular weight of human BPI is approximately 55,000 daltons (55 kD). The amino acid sequence of the entire human BPI protein, as well as the DNA encoding the protein, have been elucidated in FIG. 1 of Gray et al., J. Biol. Chem., 264: 9505 (1989), incorporated herein by reference.

The bactericidal effect of BPI has been shown to be highly specific to sensitive gram-negative species, while non-toxic for other microorganisms and for eukaryotic cells. The precise mechanism by which BPI kills bacteria is as yet unknown, but it is known that BPI must first attach to the surface of susceptible gram-negative bacteria. This initial binding of BPI to the bacteria involves electrostatic interactions between the basic BPI protein and the negatively charged sites on lipopolysaccharides (LPS). LPS has been referred to as "endotoxin" because of the potent inflammatory response that it stimulates. LPS induces the release of mediators by host inflammatory cells which may ultimately result in irreversible endotoxic shock. BPI binds to Lipid A, the most toxic and most biologically active component of LPS.

In susceptible bacteria, BPI binding is thought to disrupt LPS structure, leading to activation of bacterial enzymes that degrade phospholipids and peptidoglycans, altering tile permeability of the cell's outer membrane, and ultimately causing cell death by an as yet unknown mechanism. BPI is also capable of neutralizing the endotoxic properties of LPS to which it binds. Because of its gram negative bactericidal properties and its ability to neutralize LPS, BPI can be utilized for tile treatment of mammals suffering from diseases caused by Gram-negative bacteria, such as bacteremia or sepsis.

A proteolytic fragment corresponding to the N-terminal portion of human BPI holoprotein possesses the antibacterial efficacy of the naturally-derived 55 kD human holoprotein. In contrast to the N-terminal portion, the C-terminal region of the isolated human BPI protein displays only slightly detectable anti-bacterial activity. Ooi, et al., J. Exp. Med., 174: 649 (1991). A BPI N-terminal fragment, comprising approximately the first 199 amino acid residues of the human BPI holoprotein and referred to as "rBPI23 ", has been produced by recombinant means as a 23 kD protein. Gazzano-Santoro et al., Infect. Immun. 60: 4754-4761 (1992).

Of interest to the present application are the disclosures in PCT International Application PCT/US91/05758 having publication No. WO 92/03535 relating to compositions comprising a BPI protein and an anionic compound which compositions are said to exhibit (1) no bactericidal activity and (2) endotoxin neutralizing activity. Anionic compounds are preferably a protein such as serum albumin but can also be a proteoglycan such as heparin. In addition, Weiss et al., J. Clin. Invest., 55: 33-42 (1975) discloses that heparin sulfate and LPS bind to block expression of the permeabiilty increasing activity of BPI. Neither reference discloses neutralization of heparin by combination with BPI, however.

There continues to exist a need in the art for new products and methods for use in neutralization of heparin, inhibition of tumor and angiogenesis, endothelial cell proliferation and treatment of chronic inflammation.

DETAILED DESCRIPTION

The present invention relates to the administration of bactericidal/permeability-increasing protein (BPI) protein products for the treatment of a variety of therapeutic conditions not directly associated with bacterial infection.

While BPI is known as a potent cytotoxin for gram negative bacteria and is further known for neutralizing the adverse effects of lipopolysaccharide associated with the cell walls of grain negative bacteria, a variety of therapeutic effects for BPI protein products not directly associated with the gram negative bacterial infection have been discovered. Specifically, the invention provides methods for treating conditions not directly associated with gram negative infections including neutralization of the anti-coagulant activity of heparin, inhibition of tumor and endothelial cell proliferation including cell proliferation associated with angiogenesis and treatment of chronic inflammatory disease states such as arthritis.

The BPI protein products including biologically active fragments of BPI holoprotein which are to be administered according to the methods of this invention may be generated and/or isolated by any means known in the art. Co-owned, copending U.S. patent application Ser. No. 07/885,501, hereby incorporated by reference, discloses novel methods for the purification of recombinant BPI protein products expressed in and secreted from genetically transformed mammalian host cells in culture and discloses how one may produce large quantities of recombinant BPI products suitable for incorporation into stable, homogeneous pharmaceutical preparations.

Biologically active fragments of BPI include biologically active molecules that contains the same amino acid sequence as a BPI holoprotein, except that tile molecule lacks amino-terminal amino acids, internal amino acids, and/or carboxy-terminal amino acids of the holoprotein. By way of nonlimiting examples, such fragments include those described herein and the previously mentioned natural 25 kD fragment and a recombinant 23 kD, 199 amino acid residue amino-terminal fragment of the human BPI holoprotein referred to as rBPI23. See, Gazzano-Santoro et al., Infect. Immun. 60: 4754-4761 (1992). In that publication, an expression vector was used as a source of DNA encoding a recombinant expression product (rBPI23) having the 31-residue signal sequence and tile first 199 amino acids of the N-terminus of the mature human BPI, as set out in SEQ ID NOs: 1 and 2 taken from Gray et al., supra, except that valine at position 151 is specified by GTG rather than GTC and residue 185 is glutamic acid (specified by GAG) rather than lysine (specified by AAG). Recombinant holoprotein referred to herein as rBPI50 has also been produced having the sequence set out in SEQ ID NOs: 1 and 2 taken from Gray et al., supra, with the exceptions noted for rBPI23.

Biologically active analogs of BPI include but are not limited to recombinant hybrid fusion proteins comprising BPI holoprotein or biologically active fragment thereof, and at least a portion of at least one other polypeptide. Such proteins are described by Theofan et al. in co-owned, copending U.S. patent application Ser. No. 07/885,911, which is incorporated herein by reference in its entirety and include hybrid fusion proteins comprising, at the amino terminal end, a BPI protein or a biologically active fragment thereof and, at the carboxy terminal end, at least one constant domain of an immunoglobulin heavy chain or allelic variant thereof.

Biologically active analogs of BPI also include but are not limited to BPI protein products wherein one or more amino acid residue has been replaced by a different amino acid. For example, co-owned, copending U.S. patent application Ser. No. 08/013,801, filed Feb. 2, 1993, which is incorporated herein by reference, discloses polypeptide analogs of BPI and BPI fragments wherein a cysteine residue at position 132 or at position 135 is replaced by a different amino acid

The administration of BPI protein products is preferably accomplished with a pharmaceutical composition comprising a BPI protein product and a pharmaceutically acceptable diluent, adjuvant, or carrier. The BPI protein product composition may be administered without or in conjunction with known antibiotics, surfactants, or other chemotherapeutic agents. A preferred pharmaceutical composition containing BPI protein products comprises BPI at a concentration of 1 mg/ml in citrate buffered saline (0.02 M citrate, 0.15 M NaCl, pH 5.0) comprising 0.1% by weight of poloxamer 188 (Pluronic F-68, BASF Wyandotte, Parsippany, NJ) and 0.002% by weight of polysorbate 80 (Tween 80, ICI Americas Inc., Wilmington, DE). Such preferred combinations are described in co-owned, copending, U.S. patent application Ser. No. 08/012, 360, filed Feb. 2, 1993, the disclosure of which is incorporated herein by reference.

Effective doses of BPI and BPI protein products for partial or complete neutralization of the anti-coagulant activity of heparin and other effects described herein may be readily determined by those of skill in the art according to conventional parameters including the size of the subject, the quantity of heparin administered to the subject and the time since administration of the heparin.

Other aspects and advantages of the present invention will be understood upon consideration of the following illustrative examples. Example 1 addresses assay systems for quantification of heparin binding by BPI protein products; Example 2 describes the relative capacity of heparin to block binding of bacterial LPS to BPI protein products: Examples 3 and 4, respectively, present results of tests for the capacity of BPI protein products to inhibit thrombin or Factor Xa inactivation by antithrombin III/heparin complexes; and Example 5 relates to the effect of BPI protein products on heparin-mediated lengthening of thrombin time. Examples 6-8 relate to administration of BPI protein products of in collagen and bacterial induced arthritis animal model systems exemplifying treatment of chronic inflammatory disease states. Examples 9-10 illustrate testing of BPI protein products for angiostatic effects in a mouse malignant melanoma metastasis model system. Example 11 addresses effects of BPI protein products on endothelial cell proliferation and possible binding mechanisms involved. Examples 12-14 illustrate heparin-binding, LPS-binding and bactericidal activities for BPI protein product synthetic peptides.

EXAMPLE 1

Heparin binding assays were conducted using membrane bound natural and recombinant BPI molecules and radiolabelled heparin. Briefly, rBPI23 and holoprotein designated rBPI50 were added to wells of a 96-well microtiter plate having an Imobilon-P (Millipore, Bedford, Mass.) membrane disposed at bottom of the wells. Five μg of protein was added to each well. The wells were dried and subsequently blocked with a 0.1% bovine serum albumin (BSA) in phosphate buffered saline, pH 7.4 (blocking buffer.) Dilutions of 3 H-heparin (DuPont, NEN, Wilmington, Del.) were made in the blocking buffer and incubated in the rBPI23 containing wells for one hour at 4° C. The unbound heparin is aspirated and the wells were washed three times with blocking buffer, dried and removed for quantitation in a liquid scintillation counter. Typical assay results are graphically presented in FIG. 1. While BSA in the blocking buffer does have a low affinity and capacity to bind heparin, this was considered physiologically irrelevant and the background was routinely subtracted from the test compound signal.

Similar assays compared heparin binding by rBPI23 , rBPI50, and natural holoprotein (BPI55) with thaumatin or with wash buffer (1% BSA) as controls. In these assays, relatively little heparin binding by the natural and rBPI50 holoproteins was observed. The lesser extent of binding by rBPI50 and nBPI55 may have been the result of carbohydrate contamination of the protein preparations.

In addition, binding constants with 3 H-heparin as the ligand were determined using nonlinear function minimization with Grafit software (Erithicus Softward Ltd., Staines, UK) for rBPI23, rBPI50, protamine and thaumatin with the results shown in Table 1 below.

EXAMPLE 2

The ability of heparin and of soluble Lipid A, LPS, and Teichoic acids to compete with immobilized E. coli J5 Lipid A for binding to soluble rBPI23 were assessed. Specifically, Immulon 2 (Dynatech, Chintilly, Va.) microtiter wells were coated with E. coli J5 Lipid A at a concentration of 0.5 μg/mL in methanol (50 μL volume ). The wells were then blocked for 4 hours at 37° C. with PBS containing 0.1% BSA. Control wells were treated with 50μL of plain methanol and then blocked as above. The blocked wells were aspirated and washed twice with PBS/0.05% Tween-20. Varying concentrations of putative inhibitors were plated onto the wells in a volume of 25μL PBS, followed by 200,000 cpm of radio-iodinated rBPI23 in 25μL of PBS containing 0.1% Tween-20. The test solutions included Ra LPS from Salmonella minnesota R60 at 200μg/mL; Smooth LPS from E. coli 0113 (RIBI Immunochem, Hamilton, Mont., #R318) at 200μg/mL; Lipoteichoic acid from Streptococcus faecalis, (Sigma, St. Louis, Mo., #L-4015) at 400 μg/mL; Lipoteichoic acid from Staphylococcus Aureus, (Sigma #L-2525) at 400 μg/mL; and heparin sodium USP injection (Lypho-Med, Rosemont, Ill., #915501 ) at 400 μg/mL. Binding was allowed to proceed overnight at 4° C. with gentle shaking, after which the wells were aspirated, washed three times with PBS/0.05% Tween-20, and counted. The results as set out in FIG. 2 show a high affinity of rBPI23 for heparin and also that heparin block a greater proportion of BPI binding to Lipid A at concentrations of up to 0.1μg/mL than any of the LPS or teichoic acid inhibitors.

EXAMPLE 3

A chromostrate assay was used to determine the effect of rBPI23 on thrombin inactivation by ATIII/heparin complexes. Specifically, a Chromostrate anti-thrombin assay kit (Organon Teknika Corp., Durham, N.C.) was used to examine the inhibition of purified thrombin by preformed ATIII/heparin complexes in plasma.

The assay was performed in 96 well microtiter plates with a final volume per well of 200 μg/mL. The order of addition of assay components was as follows: diluted heparinized reference plasma (50 μL); thrombin 1nKat/mL (50 μL ); 50 μL rBPI23 or thaumatin (a control protein) at concentrations ranging from 1.0 μg/mL to 100 μg/mL; and thrombin chromogenic substrate 1 μmole/mL (50 μL). The reaction was allowed to proceed for 5 minutes and the color reaction was quantitated on a microplate reader. The assay results shown in FIG. 3 indicate that rBPI23 can effectively neutralize ATIII/heparin complexes in heparinized human plasma in a dose dependent manner. As the plasma was titrated the amount of thrombin activity increased. This was caused by a decrease in the amount of inhibitory ATIII/heparin complexes in the added plasma. The control protein, thaumatin, was essentially equivalent in effect to the buffer control at all protein concentrations.

EXAMPLE 4

A chromostrate assay was used to determine the effect of rBPI23 on Factor Xa neutralization by ATIII/heparin complexes. Specifically, the assay was conducted using a chromostrate heparin anti-Factor Xa assay kit (Organon Teknika Corp.) and was performed under fixed concentrations of Factor Xa and ATIII. Heparin concentration was varied so that a heparin standard curve was generated for determination of unknown heparin concentrations in clinical samples. The assay measured functional Factor Xa activity by the release of a chromogenic compound from a synthetic substrate. ATIII/heparin complexes neutralize Factor Xa activity, thus the amount of chromogen released was inversely related to the amount and anti-Factor Xa activity of heparin in the assay sample.

The assay was performed in 96 well microtiter plates with a final volume per well of 200 μL. Assay components were added to the microtiter wells as follows: 50 μL of purified Factor Xa (.14nKat/mL), 25 μL purified bovine ATIII (0.5 U/mL), 25 μL heparin (from 0.0 to 0.6 U/mL), 50 μL rBPI23 or the control thaumatin at various concentrations (from 3.125 μg/mL to 100 μg/mL) and 50 μL substrate (3 μmoles/mL). The reaction was allowed to proceed for 5 minutes and then the color reaction was quantitated on a microplate reader. The assay results shown in FIG. 4 indicates that rBPI23 can effectively neutralize heparin in the ATIII/heparin inhibition of Factor Xa. As the concentration of heparin is increased, the amount of rBPI23 necessary for heparin neutralization also increased. The control protein, thaumatin, was essentially equivalent in effect to the buffer control at all protein concentrations.

EXAMPLE 5

The effect of rBPI23 was determined on heparin-mediated lengthening of thrombin time, i.e., the time required for clotting of a mixture of thrombin and plasma. Thrombin time is lengthened by the presence of endogenous or exogenous inhibitors of thrombin formation, such as therapeutically administered heparin. Agents which neutralize the anticoagulant effects of heparin will reduce the thrombin time measured by the test. Human citrated plasma (200 μL) was incubated for 1 minute at 37° C. with either 15 μL of diluent (0.15 M NaCl, 0.1 M Tris, pH 7.4) or 15 μL of the diluent also containing 25 μg/mL heparin (187 units/mg). Various concentrations of rBPI23 )from 0.0 to 56 μg/mL) in a volume of 15 μL were added, followed immediately by 100 μL of thrombin reagent (Sigma Chemical Co., No. 845-4). Clotting time (thrombin time) was measured using a BBL Fibrometer (Becton Dickenson Microbiology Systems, Cockeysville, Md.). The results shown in FIG. 5 establish that rBPI23 inhibits the heparin-mediated lengthening of thrombin time. In the absence of heparin, rBPI23 had no effect on the assay even at concentrations as high as 56 μg/mL.

The results of Examples 1 through 5 show that rBPI23 binds to heparin in direct binding assays and effectively neutralizes heparin inhibition of coagulation proteases. Based on these characteristics, BPI protein products are projected to be useful in the clinical neutralization of heparin anti-coagulant effects in dosages generally corresponding functionally to those recommended for protamine sulfate, but are not expected to possess the severe hypotensive and anaphylactoid effects of that material.

A further aspect of the present invention relates to the discovery of the utility of BPI to treat and prevent the effects of chronic inflammatory disease states such as arthritis, including rheumatoid and reactive arthritis, psoriasis, inflammatory bowel disease, Crohn's disease, ulcerative colitis, lupus erythematosus, autoimmune uveitis, Lyme disease, and asthma. Exemplary methods are provided for treating subjects suffering from arthritis comprising administering an effective amount of a BPI protein product in order to prevent or treat arthritis. The BPI protein product may be administered topically, or by injection such as intraarticularly, intravenously, intramuscularly or subcutaneously or by other parenteral and non-parenteral methods.

EXAMPLE 6

The effect of administration of BPI protein products was studied in a collagen-induced arthritis model. Specifically, arthritis was induced in mice by intradermal immunization of bovine Type II collagen at the base of the tail according to the method of Stuart et al., J. Clin. Invest., 69: 673-683 (1982). Generally, mice begin to develop arthritic symptoms at Day 21 after collagen immunization. The arthritic scores of the treated mice were then evaluated in a blinded fashion over a period of 120 days for mice treated on each of days 21-25 with doses of either rBPI23, thaumatin control protein, or buffer which were injected intravenously via the tail vein.

Specifically, bovine Type II collagen (Southern Biotechnology Associates, Inc., Birmingham Ala.) was administered via intradermal injection (0.1 mg/mouse) at the base of the tail on day 0 to groups of ten male mice (Mouse/DBA/1J), each weighing approximately 20-25 g grams. rBPI23 was dissolved in 0.5 M NaCl, 20 mM sodium acetate, pH 6.0 and diluted with PBS buffer (1 mg/ml) for administration at 0.125 mg/mouse. Thaumatin protein in PBS (0.121 mg/mouse), and PBS buffer alone (0.1 ml) were administered as controls.

The results shown in FIG. 6 show that the BPI has a statistically significant effect in reducing the arthritic score of treated mice compared with the PBS buffer and thaumatin protein controls.

EXAMPLE 7

The collagen-induced arthritis model of Example 6 was used to evaluate the performance of a BPI protein product in comparison with protamine sulfate, and both thaumatin protein and buffer as controls. Specifically, rBPI23 was dissolved in 0.5 M NaCl, 20 mM sodium acetate, pH 6.0 and diluted with PBS buffer (1 mg/ml) and was administered at 0.125 mg/mouse. The other test materials were administered at the following dosages: protamine sulfate (Sigma Chemical Co) (0.13 mg/mouse), thaumatin (0.121 mg/mouse), and PBS buffer (0.1 ml). Each of four groups of ten mice received test or control materials through intravenous injection via the tail vein on each of days 28 through 32. FIG. 7 discloses the results of arthritic scores for the various treatment and control protocols evaluated at days 28-80. The stars (*) in FIG. 7 represent a statistically significant difference between rBPI23 and buffer at p<0.01 while the pluses (+) represent a statistically significant difference between rBPI23 and buffer at p < 0.05.These results show that the rBPI23 significantly reduced arthritic score for mice treated in the model system.

EXAMPLE 8

In this example BPI protein products are administered to treat reactive arthritis in a Yersinia enterocolitica reactive arthritis model according to the method of Yong et al., Microbial Pathogenesis, 4: 305-310 (1988). Specifically, BPI protein products are administered to DBA/2J mice which have previously been injected intravenously with Yersinia enterocolitica WA at a dosage calculated to induce a non-septic arthritis in the mice.

The invention also provides methods for inhibiting endothelial cell proliferation and angiogenesis by administration of BPI protein products. Examples are specifically provided which address treatment of tumors in a mouse melanoma model system.

EXAMPLE 9

According to this example, a BPI protein product, protamine, and both thaumatin protein and buffer controls were tested for efficacy in a mouse malignant melanoma metastasis model. Specifically, four groups of nine C57BL/6J mice were inoculated with 105 B16.F10 malignant melanoma cells via intravenous injection into the tail vein on day 0. Either rBPI23 (0.13 mg/mouse), protamine sulfate (0.13 mg/mouse), thaumatin (0.13 mg/mouse) or PBS buffer (0.1 ml/mouse) were intravenously administered into the tail vein of the mice on days 1, 3, 6, 8, 10, 13, 15, 17, and 19. The animals were sacrificed via cervical dislocation on Day 20 for observation of lung tissues. The lobes of each lung were perfused and inflated by injecting 3 ml water into the lung via the trachea. Superficial tumor nodules were then counted with the aid of a dissecting microscope and the number of tumors found per group analyzed for statistically significant differences. While the data was not statistically significant, animals treated with BPI23 had the lowest tumor load, followed by those treated with protamine, the thaumatin protein control and the buffer control. The lack of statistical significance (tumor number did not adequately reflect tumor size) indicated that a more specific assay methodology would be needed to determine the tumor load.

EXAMPLE 10

A BPI protein product, protamine, and both thaumatin protein and buffer controls were again tested for efficacy in the mouse malignant melanoma metastasis model of Example 9. Specifically, six groups of C57BL/6J mice were inoculated with 105 B16. F10 malignant melanoma cells via intravenous injection into the tail vein on day 0. Either rBPI23 (0.125 mg/mouse), protamine sulfate (0.125 mg/mouse), thaumatin (0.125 mg/mouse) or PBS buffer as set out in Table 2 below were intravenously administered into the tail vein of the mice on days 1, 2, 5, 7, 9, 12, 14, 16, and 19. All animals in groups A-D were sacrificed by cervical dislocation on day 20 for observation of lung tissues. The lungs were removed and placed into a beaker of cold water. The lobes of each lung were then perfused and inflated by injecting 3 ml of water into the lung via the trachea. Superficial tumor nodules are then analyzed for melanin content.

Groups E and F comprising animals treated with either buffer or rBPI23 respectively were not sacrificed but were observed once daily for mortality. FIG. 8 shows the survival data for the two groups of animals. Although all ten of the animals had died by day 43, the BPI treated mice generally survived significantly longer than the untreated mice indicating that BPI had an anti-angiogenic effect and slowed metastasis of the melanoma tumors.

According to an additional aspect of the invention, BPI protein products may be used to inhibit Kaposi's Sarcoma in a model system such as that of Miles et al., VII International Conference on AIDS, Florence, Italy, Paper 41(8), 1991.

EXAMPLE 11

Murine cerebral capillary endothelial cells (EC) as described in Bauer, Microvascular Research 37: 148-161 (1989) were passaged in Medium 199 containing Earle's salts, L-glutamine and 2.2 g/l of sodium bicarbonate (Gibco, Grand Island, N.Y., #400-100EB), plus 10% heat inactivated fetal calf serum (Irvine Scientific, Irvine, Calif.) and 1% penicillin/streptomycin (Gibco, #600-5140AG). Harvesting of the confluent cells was performed by trypsinization with trypsin-EDTA (Gibco #610-5300PG) for 3 minutes. The trypsinization was stopped by adding 10 ml of the passage medium to the flask. Proliferation assays were performed on freshly harvested EC in standard flat bottom 96 well microtiter plates. A final volume of 200 μl/well was maintained for each well of the assay. A total of 4×104 EC were added to each well with varying concentrations of rBPI23, thaumatin control protein or buffer control. After 48 hours of culture in a 5% CO2 incubator, 1 μCi of [methyl-3 H] thymidine in 10 μl of Medium 199 was added to each well. After a 24 hour pulse, the EC cells were harvested by trypsinization onto glass microfiber filters and incorporated [3 H]thymidine was quantitated with a gas proportional solid phase beta counter.

Concentration dependent inhibition of EC cell proliferation by rBPI23 is shown in FIG. 9. No effect was observed when similar concentrations of thaumatin or equal volumes of the buffer were added to the wells. The first inhibition of proliferation is observed at 12.4 μg/ml rBPI23 and the effect appears to be maximal at 50 μg/ml. The growth of the EC cells is known to be dependent on FGF-2 (bFGF) in the calf serum and FGF-2 requires cell surface heparan for receptor activation (Yayon et al., Cell 64: 841-848, 1991). Without intending to be bound by a theory of the invention, it is believed that rBPI23 bound to cell surface heparan on the EC cells interferes with the activation of the cells by FGF-2.

Direct binding studies of rBPI23 on the EC cells were performed by harvesting the 10x passaged cells from a confluent flask and resuspending the trypsinized cells in 12.5 ml of culture medium. 0.5 ml of the suspension was added to each well of a standard 24 well tissue culture plate and incubated overnight. The plate was washed with 0.1% bovine serum albumin in phosphate buffered saline containing calcium and magnesium. (Gibco.) After washing, 0.5 ml of the BSA/PBS was added per well. Preliminary experiments indicated that 50 ng/ml of 125 I-labeled rBPI23 added to the wells produced approximately 30,000 specific cpm after a 3 hour, 4° C. incubation with 3x washing in PBS and lysis with 1 M NaOH from gamma counting of the lysate.

The specific binding of 50 ng/ml 125 I-labeled, "hot" rBPI23 to the EC cells could be competed by addition of 20 μg/ml heparin (Sigma, Grade I). Similar competition was observed for unlabeled ("cold") rBPI23 added to the binding culture. The combination of unlabeled rBPI23 with heparin (concurrently added or pre-mixed prior to addition) could not reduce the binding below the heparin only competition (FIG. 10). These data indicate that rBPI23 binds to endothelial cells via heparin-like molecule and that this binding appears to interfere with EC cell proliferation to a heparin binding growth factor (FGF-2).

In order to assess biological properties of peptide fragment BPI protein products, 15-mer amino acid synthetic peptides based on the 23 kD amino terminal fragment of BPI were prepared and evaluated for heparin-binding activity, activity in a Limulus Amoebocyte Lysate Inhibition (LAL) assay and bactericidal activity. Specifically, 47 synthetic peptides each comprising 15 amino acids and overlapping the adjacent peptides by 11 amino acids were prepared, in duplicate, based on the sequence of rBPI23 described above.

Peptides were simultaneously synthesized according to the methods of Maeji et al., Immunol. Methods, 134: 23-33 (1990) and Gammon et al., J. Exp. Med., 173: 609-617 (1991 ), utilizing the solid-phase technology of Cambridge Research Biochemicals Ltd. under license of Coselco Mimotopes Pty Ltd. Briefly, the sequence of rBPI23 (1-199) was divided into 47 different 15-mer peptides that progressed along the linear sequence of rBPI23 by initiating a subsequent peptide every fifth amino acid. This peptide synthesis technology allows for the simultaneous small scale synthesis of multiple peptides on separate pins in a 96-well plate format. Thus, 94 individual pins were utilized for this synthesis and tile remaining to pins (B,B) were subjected to the same steps as the other pins without tile addition of activated FMOC-amino acids. Final cleavage of the 15-mer peptides from the solid-phase pin support employed an aqueous basic buffer (sodium carbonate, pH 8.3). The unique linkage to the pin undergoes a quantitative diketopiperazine cyclization under these conditions resulting in a cleaved peptide with a cyclo(lysylprolyl) moiety on the carboxyl-terminus of each peptide. The amino-termini were not acetylated so that the free amino group could potentially contribute to anion binding reactions. An average of about 15 μg of each 15-mer peptide is recovered per well.

EXAMPLE 12

The synthetic BPI protein product peptides described above were subjected to a heparin binding assay according to the methods described in Example 1. The results, as shown in FIG. 11, indicate the existence of three separate functional domains with heparin binding activity; the first extending from about amino acids 21-55; the second extending from about amino acids 65-107; and the third extending from about amino acids 137-171. Material from blank control pins had no heparin binding effects.

EXAMPLE 12

The synthetic BPI protein product peptides described above were Limulus Amoebocyte Lysate (LAL) inhibition assay to determine LPS binding properties. Specifically, the synthetic BPI peptides were mixed in Eppendorf tubes with a fixed concentration of E. coli 0113 LPS (4 ng/ml final) and incubated at 37° C. for 3 hours with occasional shaking. Addition controls comprising 0.05 μg/mL were also tested. Following incubation, 360 μl D-PBS was added per tube to obtain an LPS concentration of 200 pg/mL for the LAL assay. Each sample was then transferred into Immulon II strips (Dynatech, Chantilly, Va.) in volumes of 50 μl per well.

Limulus amoebocyte Lysate (Quantitative chromogenic LAL kit, Whitaker Bioproducts, Inc., Walkersville, Md.) was added at 50 μl per well and the wells were incubated at room temperature for 25 minutes. Chromogenic substrate was then added at a volume of 100 μl per well and was well mixed. After incubation for 20 to 30 minutes at room temperature, the reaction was stopped with addition of 100 μl of 25% acetic acid. Optical density at 405 nm was then measured in a multiplate reader (Vmax, Molecular Dynamics, Menlo Park, Calif.) with the results shown in FIG. 12 in terms of percent inhibition of LPS. The data in FIG. 12 indicate at least three major domains with significant LAL inhibition; the first extending from amino acids 17-55; the second extending from about amino acids 73-99 and the third extending from about amino acids 137-163. Other individual peptides also exhibit LAL inhibition. In contrast, material from blank control pins did not exhibit LPS neutralizing effects as measured by the LAL assay.

EXAMPLE 14

The synthetic BPI protein product peptides were tested for bactericidal effects against the rough mutant E. coli J5 bacteria in a radial diffusion assay. Specifically, an overnight culture of E. Coli J5 was diluted 1: 50 into fresh tryptic soy broth and incubated for 3 hours at 37° C. to attain log phase. Bacteria were then pelleted at 3,000 rpm for 5 minutes in a Sorvall RT6000B. 5mL of 10 mM sodium phosphate buffer (ph 7.4) was added and the preparation was re-centrifuged. The supernatant was decanted and 5 mL of fresh buffer was added, the bacteria were resuspended and their concentration was determined by measurement of absorbance at 590 nm. Absorbance of 1.25×109 CFU/mL suspension equals 1.00. The bacteria were diluted to 4×106 CFU/mL in 10 mL of molten underlayer agarose (approximately 45° C.) and inverted repeatedly to mix with 15 mL polypropylene tubes used for this purpose.

The entire contents of tile tube were poured into a perfectly level square petri dish and distributed evenly by rocking the dish side to side. The agarose hardened in less than 30 seconds and had a uniform thickness of about 1 mm. A series of wells were then punched into the hardened agarose using a sterile 3 mm punch attached to a vacuum apparatus. The punch was sterilized with 100% alcohol and allowed to air dry.

10 μL of the synthetic BPI peptides were carefully pipetted into each well. As controls, pH 8.3 buffer was added to a separate well (as positive controls, 5 μg/mL and 1 μg/mL concentration of rBPI23 was also added. In addition, products from tile blank pins B and B were tested as controls. The plate was allowed to incubate at 37° C. for 3 hours and 10 mL of molten overlayer agarose (at approximately 45° C.) was then added into the level petri dish, allowed to harden and incubated overnight at 37° C. A clear zone was seen against the lawn of bacteria in those wells having bactericidal activity. In order to visually enhance this zone, a dilute Coomassie solution (0.002% Coomassie Brilliant Blue, 27% methanol, 15% formaldehyde (37% stock solution) and H2 O) was poured over the agar and allowed to stain for 24 hours. The bacterial zones were measured with a Mitutoyo micrometer.

The results of the assay are shown in FIG. 13 where the only synthetic BPI peptide seen to have bactericidal activity was a fragment corresponding to amino acids 85-99. The positive rBPI23 controls also had bactericidal effects while the buffer and blank pin controls did not.

The results of this bactericidal assay along with the heparin binding and LAL assays indicate that there exist small synthetic BPI peptides with one or more of bactericidal, heparin binding and LPS neutralizing effects and that there exist three distinct separate functional domains within the 23 kD amino terminal fragment. The most active domain, characterized by activity in all three assays, resides between amino acids 73-99. One specific peptide 86-99 demonstrated activity in all three assays. A second domain resides between amino acid residues 25-44 and the third domain is composed of residues 117-128 and 143-163. The third domain is separated by a CSSCSS amino acid sequence that presumably is involved in a disulfide bond which brings these two minor regions in close 3-dimensional proximity within the native rBPI23 molecule to create a third LPS/heparin binding domain.

Numerous modifications and variations in the practice of the invention are expected to occur to those skilled in the art upon consideration of the presently preferred embodiments thereof. Consequently, the only limitations which should be placed upon the scope of the invention are those which appear in the appended claims.
